Famous Phrases 6

In Cryptography teasers, a phrase or expressions has been encoded in some way (frequently by replacing letters with other letters). You need to figure out the encoding method and then decode the message to find the answer.

Each of the words in the following cryptograms is missing a letter, indicated by "_". These missing letters form two quotes, along with the person who said each quote. There are at least two letter options for each word, so you will have to determine the appropriate missing letters to solve the cryptograms (eg, "BO_N" could be "BOON" or "BORN", the missing letter being either "O" or "R"). "/" separates the individual words of the quote, "+" separates the individual letters of each word in the quote, "~" separates the person from the quote.
